Abstract
One of the most critical threats to the reliability and robustness for file system is harboring bug (silent data corruption). In this research we focus on checksum mismatch since it occurs not only in the user data but also in file system. Our proposed solution has the ability to check this bug in file system of Linux. In our proposed solution there is no need to invoke or revoke checker utility, it comes as the integrated part of file system and has the ability to check upcoming updates before harboring bug make unrecoverable changes that leads significant data loses. Demonstration testing shows satisfactory results in file server and web server environments in terms of less memory consumption and avoidable delay in system’s updating.
